In this summer’s Boyhood, Richard Linklater summed up 12 years of a kid’s life into one feature-length movie. Now the documentary 21 Years: Richard Linklater will do the same to the filmmaker’s career.

Directed by Michael Dunaway and Tara Wood, the documentary is based on the idea that “the first 21 years defines the career of an artist.” In Linklater’s case, that means looking at everything he’s done from Slacker to Boyhood… which are actually 23 years apart, but we’ll let it slide. Hit the jump to watch the 21 Years Richard Linklater trailer.
